What are the symptoms of respiratory acidosis?
Headache and tremors
Trousseau's and Chvostek's signs
Crackles and rhonchi upon auscultation
Hyperactivity and reduced serum ionized calcium levels
The Correct Answer is A
A. Headache and tremors:
Respiratory acidosis leads to CO₂ retention, causing cerebral vasodilation, resulting in headache and neuromuscular irritability like tremors.
B. Trousseau's and Chvostek's signs:
These are signs of hypocalcemia, commonly seen in respiratory alkalosis, not acidosis.
C. Crackles and rhonchi upon auscultation:
These are lung sounds that might be present in respiratory conditions (like pneumonia or CHF) but are not specific symptoms of acid-base disturbances like respiratory acidosis.
D. Hyperactivity and reduced serum ionized calcium levels:
These findings are consistent with respiratory alkalosis, not acidosis.

Correct Answer is D
Explanation
A. Mitral stenosis:
Mitral stenosis is narrowing of the mitral valve, often due to rheumatic heart disease, not IV drug use or infection.
B. Angina pectoris:
Angina is chest pain due to ischemia, not infection or vegetation on heart valves.
C. Aortic insufficiency:
Aortic insufficiency is leakage of the aortic valve, leading to volume overload, not typically associated with infection and petechiae.
D. Infective endocarditis:
IV drug users are at high risk for infective endocarditis. Symptoms include fever, chills, weakness, petechiae, and vegetations seen on echocardiogram.
